First, I'm quite certain that NOBODY has said "Five Rangz" 13013291328 times. Regardless, there is a factual nature to the reminder that five RINGS is an objective and factual measure of "things that matter" superioriity. It's the most natural response when you beat us ONE TIME in 30-some-odd years and we can still say that we have been better than Florida for the majority of that same time period, and have won more championships.
Second, the one thing that you'll never acknowledge is that, if the tables were turned and Florida had five rings, you would flaunt it over everyone else with fewer titles. That's the great thing about winning national championships - when you do it, you get to say it. And all the other lesser teams are going to snipe and complain and act as if we are "living in the past". Doesn't fvckin' matter. Notre Dame hasn't won in a while, but they still get to tout their titles. THAT is what college football bluebloods get to do, and if Florida ever gets to Miami's level, you'll do the EXACT SAME stuff that we do. Talk about how many times you've won. The spoils of greatness.
Third, I'm not even going to address the "I saw one thing happen at a stadium one time" argument, because it is ridiculous. I've traveled to away games all over the place (and as a member of a very hated fanbase, as I'm sure you would agree), and I've been treated poorly in nearly every situation, without having done anything to deserve such treatment beside being a UM alum. And, yes, I've been to every UM-UF game (regardless of location) since 1986, not that there have been many of them. While I am sorry that you had one bad experience at Hard Rock, I've had multiple bad experiences in Gainesville every single time I've gone, including at basketball and baseball games.
Finally, circling back to "Five Rangz", you cannot cite ANYTHING, outside of one blog or twitter handle or some such, that INITIATED the phrase "five rangz" by a Miami fan, alum, or booster. You refuse to acknowledge that while you have HEARD the phrase, it was a spoken phrase. Therefore, the written characterization of "Five Rings" as "FIVE RANGZ" is absolutely the creation of a Miami rival trying to stoke race-oriented feelings by turning a simple phrase into a mispronounced and misspelled bastardization. I don't care if you complain about "Five Rings" on your website, but to take the time to write it as "FIVE RANGZ" is an intentional "ebonicization" of a phrase.
You can minimize it or ignore it or actively blow it off, but that's the truth.
